I don't have to because I'm slow. I'm making an examination room It is my fault, and it unfortunately. I need to learn this course next year and it is waste of time.
I'm not sure, because I'm slow, I went into the exam room. It is my fault, and it's very disappointing. I have learned this year and it is very time consuming.
I didn't get into the examination room, because I'm late, I class the wrong room. It was my fault, and it's a pity. I have to learn the subject in front and it was a waste of time.
